RESUMEN
INTRODUCTION: We attempted to supplement traditional insecticide spraying by treating peridomiciliar food sources with a powder formulation. METHODS: Two groups of houses were treated with deltamethrin suspension concentrate (SC), one of which had its primary peridomestic food sources treated with deltamethrin 2P. RESULTS: Triatoma brasiliensis was the most commonly captured triatomine. Birds, dogs and rodents were the major food sources identified by the precipitin reaction; 554 domestic animals received powder treatment. A sharp reduction in infestation rates was observed in the two groups up to 360 days after spraying. CONCLUSION: The combination SC + 2P did not improve the control of triatomines.
